Ear plug



FIG. 1 is a side elevation view of the invention;

FIG. 2 is a top view of the invention; and,

FIG. 3 is a bottom view of the invention.

The ear plug is symmetrical about its longitudinal axis, whereby front, rear and side views of the ear plug are all illustrated by the side elevation view of FIG. 1. The broken lines shown in the figures are for illustrative purposes only and form no part of the claimed design. 

I claim the ornamental design of an ear plug, as shown and described.
